There is a case study of ARGO buoys possibilities for Arctic Ocean scientific investigations with innovative ocean technologies on the base of geospatial measurement and information systems that are part of decision support systems. The compiled data base of some ARGO buoys (DB ARGO) penetrated into arctic and subarctic waters from Atlantic (DB ARGO ATL) developed. It is intended to research the patterns of Atlantic Waters penetration into the Arctic Ocean. One of these buoys had unique long Odyssey from warm waters near southern coast of Nova Scotia to high latitude arctic area near northern cap of Novaya Zemlya. This trip began 2008 summer and lasted near five years. Over 180 vertical profiles of temperature and salinity provided with 10 days interval and transferred to ARGO Data Center. Over year this buoy moved inside depth of Barents Sea dragged by Atlantic Waters. It crossed area of Stockman gas-oil field in 2012 and then came to northern cap of Novaya Zemlya where ended functioning at 2013 early spring. Till now it is the only ARGO buoy trip in the Barents Sea. The measurement results obtained during this drift indicated a significant inflow of atypically warm Atlantic Waters into high latitude area between Franz Josef Land and Novaya Zemlya. It was accompanied by later dates of ice appearance in this area. This case study clearly demonstrates the ARGO buoys resources for Arctic Ocean scientific investigations including patterns and scenarios of climate change for Arctic with Atlantic Waters engagements.

Here we used data that was collected and made freely available by the International Argo Project http://www.argo.net and national initiatives that contribute to it. Argo is a pilot programme of the Global Ocean Observing System. The Ministry of education and science of Russia provided financial support for this research with the state order 2014/166 and state contract 14.515.11.0002. [ABSTRACT FROM AUTHOR]

Fieldwork was conducted in two stages: 23-27.06.2013 and 17-22.07.2013, in the Eastern Gulf of Finland by sailing-motor catamaran «Centaurus II» in the framework of the TopCons Project. Main scientific direction of the summer oceanographic surveys was conduction of experimental research for environmental monitoring of marine ecosystem in the Eastern Gulf of Finland. Full complex of hydrological and hydrochemical observations has included measurement of salinity and water temperature, flow parameters in the bottom layer at four stations within the specified polygon, sampling and their quantitative chemical analysis. Authors present the main analysis results of hydrophysical and hydrochemical fields for the period of observations. The fieldwork is done in the framework of the SOUTH-EAST FINLAND - RUSSIA ENPI CBC PROGRAMME 2007-2013 Project "TOPCONS - Transboundary tool for spatial planning and conservation of the Gulf of Finland", Grant Contract 2011-022-SE511. The advanced analyzing made with financial support of the Ministry of education and science of within the state order 2014/166 and state contract 14.515.11.0002. [ABSTRACT FROM AUTHOR]
